Ichthys meaning
The ichthys is a fish used by early Christians as a confession. The Greek word ἰχθύς was read as an acronym for “Jesus Christ, God’s son, savior.” It is a sentence as much as a picture.
A fish that is also a sentence.
The name. Greek ichthys, fish. Read as an acrostic: Iēsous Christos Theou Yios Sōtēr — Jesus Christ, son of God, savior.
Where it comes from
The acrostic is the early Christian content of the sign. Gospel scenes sit behind it too: fishers of people, the feeding of crowds. It could be scratched quickly, and it did not depict the execution. That discretion is practical, not cute. The modern chrome fish on a car is the same sentence, usually without the Greek.
Christian
A creed in five letters
Each letter is a word. The drawing is a way of writing a confession where a paragraph would be unwise or too slow. If you only see “fish,” you have the disguise and not the line it was hiding.
Geometry
Not the vesica, quite
The outline is an almond, and almonds are how the vesica piscis gets drawn. The name “fish bladder” for that figure is a later Latin rhyme, not the origin of the ichthys. They meet in Christian art. They do not start as one symbol.
